Proper Train Whistle/horn signals for all occasions

[TR-Flyer]

Can anyone tell me or point me to a source of information, that tells you what the proper number and length of "blasts" are to be used by operating trains to signal various messages? i.e. when approaching a crossing, what is the proper way for a train to blow it's horn to let me know i'm about to be turned into protoparticles?
Thanks!

What's you interest here? Did you post via your laptop while stuck on a grade crossing?

Kidding aside, there should be some 1:1 scale railroaders around here that can answer. Added question - do the 'codes' change from railroad to railroad?

Whistle Signals

Here's a "cute" page about Signals. It has most of them. and NO the sigs DO NOT change EVER!!!!!

It is so that: ANY employee on ANY railroad in NA will know ANY signal given, by ANY Railroad.

I don't know about international Railroads. Anyone else????
